If you follow me on Facebook, you were probably expecting a chicken wing recipe today.

Crispy, baked sweet potato fries are obviously not chicken wings. And this isn’t some kind of foodie mind game where I’m going to trick you into thinking you’re eating chicken wings instead of sweet potatoes. (Vegan cauliflower buffalo wings, anyone?)

These are most definitely oven baked sweet potato fries.

So what happened to the chicken wings? First of all, they were delicious.

But I just hated the pictures I took. So I’ll have to make them again. What. A. Shame. Note the heavy sarcasm there.

I have a lot of love for sweet potato fries. They’re so addicting.

Basically everyone knows how to bake a sweet potato but today, we’re baking sweet potatoes as fries. The most delicious, crispy, baked sweet potato fries.

And you don’t have to feel too guilty about them because they’re baked instead of fried and sweet potatoes are a good-for-you veg. I’m not saying that these fries are a health food but I also wouldn’t say they’re in the bad-for-you category either.

But I’m not a nutritionist so please take everything I say with a grain of salt. Also, salt is really good on fries 🙃

So here’s how to make sweet potato fries! I soaked these fries overnight in the fridge in a bowl of water. You could soak them for less, about 2 hours, but don’t skip the soaking process!

Apparently, soaking potatoes in cold water helps to remove the starch from the outside of the potato. It helps make the fries crispy on the outside and nice and soft in the middle. And remember, we’re baking these fries so we can use all the help we can get in the crispy department.

Another note of importance, the size of these baked sweet potato fries. I cut them relatively thin. Not matchstick thin but a little thinner than the standard french fry. When you’re cutting them, picture a McDonald’s fry.

That’s the size you’re aiming for. I find that cutting the sweet potatoes a little bit smaller and thinner helps them bake up a little more evenly. The insides get nicely cooked without the outside burning.

If you are looking for another delicious appetizer to try, you should try Wholesome Yum’s Zucchini Fries Recipe.  It’s low carb, healthy and would be a great snack to have with these sweet potato fries on game day!

Also if you have leftover baked or mashed sweet potatoes, use it to bake a batch of Gluten Free Sweet Potato Muffins or Sweet Potato Bread (in The Gluten-Free Quick Breads Cookbook). SO good!

  • 1 large sweet potato peeled and cut (about 1 lb.)
  • 1 Tbsp. cornstarch
  • 1 Tbsp. extra virgin olive oil
  • 1/2 tsp garlic salt
  • 1/4 tsp ground black pepper
  • 1/4 C mayonnaise
  • 1/4 C. spicy brown mustard
  • 2 Tbsp pure maple syrup


  • Peel and cut your sweet potato into thin fries (think McDonalds fry size). Soak in water overnight in the refrigerator.
  • Pre-heat oven to 425 degrees and line two baking sheets with parchment paper. Drain the sweet potatoes and dry really well on a clean kitchen towel.
  • Combine mayonnaise, spicy brown mustard and maple syrup in a small bowl. Set aside.
  • In a large bowl, toss the sweet potatoes and cornstarch together until the sweet potatoes are coated. Toss with the olive oil, garlic salt and pepper.
  • Divide the sweet potatoes between the two baking sheets and spread them out so that they are not touching each other. Bake at 425 degrees for 15 minutes. After 15 minutes, stir the fries and rotate baking pans as needed. Bake for another 10-15 minutes. Check frequently aftter the 10 minutes and remove fries as they are done. Overcooked fries will burn and larger fries will take longer to bake. Serve immediately with the maple mustard dipping sauce.

    Tried these tonight and they were great! I soaked the sweet potatoes for 2 hours and they came out perfectly. I used some of the dipping sauce to put on my vegan sausage on a bun that I had with the potatoes. I now have a foolproof way of making the best sweet potato fries, thanks!

  2. MN farmers wife says:

    Totally yummy!

  3. Maya says:

    Hey, just a quick question…what is the reason behind soaking the potatoes overnight? thank you 🙂

    • Sharon says:

      Soaking draws the starch out so it’ll help them get crispier when baking. If you don’t want to soak them overnight, just soak them a few hours before you plan on making them. I just prefer prepping the night before when I’m getting dinner ready to save me some time the next day 🙂

    I made the sauce for a dinner party to dip sweet potato tater tots in (I didn’t make the fries in this recipe, just the dipping sauce). Everyone loved it! Tangy and sweet and oh-so-yummy! Some people also slathered it on the meatloaf sliders that were the main dish, and they said it was wonderful. Thanks for sharing!

  5. Tracy says:

    I love sweet potato fries! And having an amazing sauce makes them even better!

  24. These look good, even though I’m not a huge sweet potato fan. I never heard of the cornstarch trick or the presoaking. Whenever I try making baked fries they are never crispy on the outside–just kind of soggy. :-/

  25. Maria says:

    Oh my goodness, this looks amazing! I LOVE sweet potato fries, and that dipping sauce sounds AMAZING!

  26. I love sweet potato fries! And a maple mustard dipping sauce?! That sounds delicious!
